I've had them both for a couple of months now. She doesn't seem to be skinny, she looks healthy, most of the time she catches at least one. What I'm really concerned about is that I want to add a few more firebelly's to the tank but I'm afraid she could get starved out with more competition. Is there something else I could feed her or should I try putting her in her own tank and try to get her to eat from tongs?
